The Savings Bond Wizard no longer is available to be updated. However, the Savings Bond Calculator offers some of the same features and you can export your bond inventory from the Wizard to the Calculator.
Treasury Direct has issued instructions on how to do it at https://www.treasurydirect.gov/indiv/to ... wizard.htm

I completed the transfer to the calculator of my 105 bonds. It works, but I preferred the Wizard....maybe it is because I am used to the Wizard more. I am pleased, though, that all my bond values are there and I can look ahead to see the value of them for each of the next 6 months as I could with the Wizard.

I prefer the calculator and converted to it a few years ago.
Once you save your inventory to an HTML file, you can reconnect to update values and bonds.
The problem is if you miss entering a bond they get out of sequence.

Saved the files as directed, but the calculator did not work for me. Have three sets/files of bonds. The first one came up, once and only once -- but not with a new date, and never again. The other two files never would open even once in the calculator.

WHY, WHY, WHY did Treasury take away a tool that people used, liked, and had the files already built for (hundreds of bonds)? VERY frustrating and disappointing.

Are you using the serial number of your U.S. Savings Bonds in the Calculator? I have seen some internet discussion concerning security issues, that in listing the Savings Bonds data in the Calculator, it is prudent to exclude the serial numbers.

Somewhat bemused that no third-party app provider has stepped into the void and offered a replacement for SBW. But that sends a signal: not too many of us old fools still messing around with their quaint savings bonds

BMW, maybe I can help your problem. I also have several different bond lists/files, one for me, one for each child and one for parents. Figured out (with tip in the instructions) that you have to delete your browsing history every time you open up a different file/set of bonds. It's a pain but it works. Otherwise I had the same problem you did. So after you view one file, close that tab, delete browsing history, then open the new file. My browser is IE 11.

Have any of you just converted from paper? I'm considering it now that I no longer have easy access. If you have do you know if you can just import the Wizard file to do the conversion rather than hand-entering every bond again?

The online procedure is still the same. One needs to enter one bond at a time (serial number, amount and purchase month) and there is not an option to upload such information.

Hmm, worst case you could email your savings bond wizard files to someone who still has the wizard, and they could export and email you the exported file back. I think I still have my wizard installed.

I am attempting to download the Dec 2018-May 2019 Savings 'Bond Value Files. All I get is numbers gibberish. The earlier one in May worked fine. Is anyone successfully downloading it?

The Savings Bond Value Files are "numbers gibberish" except to software that understands the file format. Are you using the same software on the Dec 2018-May 2019 file as you used with the May file (presumably the one with the URL https://www.treasurydirect.gov/indiv/tools/sb201806.asc)? If using the same software, are you sure that you used it on a Savings Bond Value File, as opposed to some other file with a different format that software was written to use?

Thanks. Yes,I am using everything the same. Are YOU downloading? I have sent an email to the Treas to see what they say.

I have downloaded Savings Bond Value Files in the past and used them with software that understands the format of those files.

I doubt if the, no longer supported, Savings Bond Wizard used a Savings Bond Values file. An older version of Savings Bond Wizard - Updating the Database web page indicates that its database could be manually updated by downloading a file named sbwcrv.exe, running the Savings Bond Wizard, and using its Tools menu bar to have the Savings Bond Wizard use the downloaded file to update its database of redemption values.

I am no longer using the Wizard and I didn't last May either. Since then I used the Savings Bond Calculator which is what I am referring to.. It worked perfectly 6 months ago.

The Savings Bond Calculator worked correctly for me when I tried it a few minutes ago on a saved inventory. It reported the redemption values for 05/2019, after changing the "Value as of:" and pressing the "UPDATE" button on the "Calculate the Value of Your Paper Savings Bond(s)" page.

The Savings Bond Calculator does not depend on a Savings Bond Value File stored on a user's computer.
